- Some questions frequently asked by houseowners : how do magnets work at the atomic level?
♥ i know the basics about how magnets work and interact. but at the atomic level, what causes a metal to be magnetic. also, when two magnetic substances interact, its there and electron flow of some sort? or at least electron transfer? i am really curious as to what happens at that level.why k2o2 is possible and ko is not in terms of atomic structure? (10 points)?
♥ okay. the essay i have to write for chem class is much more extensive than that, but i don't understand the above statement at all and its due tomorrow. please please save me!!!! i really need to do well in that class, and i'm trying my hardest. i just sort of need to understand what it means in the simplest of terms. please and thank you again. also, we're just in unit 5 of high school chemistry, so think of it in the simplest of terms. it's not supposed to be too hard. she also put in a note that goes like this: note: the o2 used here is a polyatomic anion o2-2 (-2 is negative two square)describe bohr's atomic model of the atom applied to the emission spectrum of hydrogen.?

♥ briefly (in one to three sentences) explain each of the following in terms of atomic structure: (a) in general, there is an increase in the first ionization energy from li to ne. (b) the first ionization energy of b is lower than that of be. (c) the first ionization energy of o is lower than that of n. (d) the first ionization energy of na is lower than that of li and that of ne.
